Abstract: A display device includes a pixel unit including a sensing region where pixels are disposed at a first pixels per inch (PPI) and a display region where pixels are disposed at a second PPI; a touch sensor unit disposed on the pixel unit, and including a first touch sensor region where touch sensors are disposed at a first electrode density and a second touch sensor region where touch sensors are disposed at a second electrode density higher than the first electrode density; a display panel driver configured to drive the pixel unit; and a touch sensor driver configured to change at least one of a voltage level of a driving pulse applied to the first touch sensor region and an accumulated number of the touch signals sensed from the first touch sensor region based on the touch signals sensed from the first touch sensor region overlapping with the sensing region.
